- Abstract
A 37-year-old man with a history of Kawasaki disease presented with total occlusion of the right coronary artery. The patient underwent percutaneous coronary intervention (PCI) with excimer laser coronary angioplasty (ELCA) and plain old balloon angioplasty (POBA). Three months after PCI, a coronary aneurysm with restenosis was detected at the PCI site, and PCI was performed again using a small balloon. The aneurysm healed three months after the second PCI procedure. This is the first report describing the long-term outcome after an aneurysm caused by PCI with ELCA and POBA.

- Abstract
Objectives: This study examined radiographic changes in local and global spinal alignments and clinical outcomes following tumor resection without spinal fixation in patients with lumbar dumbbell tumors (LDTs)., Methods: We included 28 patients with LDTs who were followed for at least two years after surgery. We analyzed variations in the outcome variables by measuring individual coronal and sagittal parameters from radiographs. Clinical outcomes were assessed using the modified McCormick scale (MMCS), the Japanese Orthopaedic Association (JOA) score, and the visual analog scale (VAS). To evaluate the impact of tumor location on these outcomes, we categorized the patients into three groups based on tumor location: Upper (T12-L1), Middle (L2-3), or Lower (L4-S1) group., Results: The local and global spinal parameters (including Cobb angle, cervical lordosis, T1 slope, thoracic kyphosis, thoracolumbar kyphosis, lumbar lordosis [global, upper, middle, lower], sacral slope, pelvic incidence, pelvic tilt) did not show significant changes after surgery. Preoperatively, all patients experienced gait disturbances, but at the final follow-up, nearly all of them (27 cases, 96.4%) could walk without support. The JOA score and VAS demonstrated significant postoperative improvements. There were no statistically significant group differences in postoperative coronal and sagittal profiles or clinical outcomes among the upper, middle, and lower groups., Conclusions: Tumor resection without spinal fixation had no substantial impact on local and global spinal alignments and led to satisfactory clinical outcomes, suggesting that spinal fixation may not always be necessary when resecting LDTs., (Copyright © 2024.

- Abstract
Introduction: the most frequently used first-line treatment in patients with advanced hepatocellular carcinoma (HCC) is atezolizumab plus bevacizumab. Upon progression after this treatment, the standard of care in many countries is sorafenib, due to the lack of reimbursement for other drugs. Several randomized trials are currently underway to clarify the best second-line therapy in patients with HCC. This real-world study aims to compare outcomes reached by lenvatinib and sorafenib second-line therapy in this setting., Methods: the overall cohort included 891 patients with HCC from 5 countries treated with atezolizumab plus bevacizumab in first-line setting between October 2018 and April 2022. At data cut-off (May 2022), 41.5% of patients were continuing first-line treatment, 5.5% were lost at follow up, and 53.0% of patients had progressive disease after first-line therapy. 51.5% of patients with progressive disease received a second-line treatment, while 48.5% didn't receive any subsequent therapy. Between patients receiving second-line treatment, 11.1% patients underwent transarterial chemoembolization, 21.0% received sorafenib, 35.4% underwent lenvatinib, and 32.5% were treated with other drugs., Results: lenvatinib second-line subgroup achieved a median overall survival (mOS) of 18.9 months, significative longer (p = 0.01; HR: 2.24) compared to sorafenib subgroup that reached a mOS of 14.3 months. The multivariate analysis highlighted Albumin-Bilirubin 1 grade [p < 0.01; hazard ratio (HR): 5.23] and lenvatinib second-line therapy (p = 0.01; HR: 2.18) as positive prognostic factors for OS. The forest plot highlighted a positive trend in terms of OS in favor of patients treated with lenvatinib second-line regardless of baseline characteristics before first-line therapy., Conclusion: these results suggest that, in patients with HCC progressed to first-line atezolizumab plus bevacizumab, lenvatinib second-line therapy is associated to an improved survival compared to sorafenib., (S.

- Abstract
Study Design: Retrospective comparative study OBJECTIVES: To investigate whether the presence or absence of preoperative lower extremities neurological symptoms (LENS) influences clinical outcomes following tumor resection in patients with cervical intradural extramedullary (IDEM) tumors., Setting: The single institution in Japan., Methods: Ninety-two patients with cervical IDEM tumors requiring surgical resection were included. Based on the degree of preoperative LENS assessed using the modified McCormick scale (MMCS), patients were categorized into LENS (-) and (+) groups. Demographic and surgical characteristics were compared between both groups., Results: There were no significant differences observed in sex, tumor location, tumor size, surgical time, estimated blood loss, approach for tumorectomy, or tumor histopathology between the two groups. Additionally, the overall surgical outcomes were favorable for both groups. At the final follow-up, 91.1% of the patients in the LENS (+) group were able to walk without support. Improvement in LENS was observed after surgery in most patients with preoperative MMCS II-IV, but it persisted in approximately 40% of patients with preoperative MMCS V. In the LENS (+) group, there were no significant differences in demographic or surgical data between the patients with MMCS I and II-III at the final follow-up., Conclusions: Regardless of the presence or absence of preoperative LENS, clinical improvement was observed after tumor resection in most patients with cervical IDEM tumors. These findings suggest that neurological status is likely to improve sufficiently if tumor resection is performed before preoperative LENS deteriorates to an extremely severe stage as MMCS V., (© 2024.

- Abstract
Background: The aims of this study were to identify clinically significant biomarkers of a response to atezolizumab plus bevacizumab (ATZ + BV) therapy and to develop target strategies against unresectable hepatocellular carcinoma (u-HCC)., Method: We first investigated the potential of circulating tumor DNA (ctDNA) to serve as a biomarker for predicting the therapeutic outcome in 24 u-HCC patients treated with ATZ + BV therapy. Next, we analyzed levels of immune-related cytokines in blood samples from 134 u-HCC patients who received ATZ + BV. For this, serum immune-related molecules or cancer-immune cycle-related molecules that have been reported in HCC patient sera, namely CD274, LAG-3, CCL2, 4, 5, CXCL1, 9, 10, 12, 13, CX3CL1, CCR5, IFNγ and IL-6, 8 were measured using enzyme-linked immunosorbent assay., Results: More than 1% of variant read frequency (VRF) mutations were found in TP53, APC, PIK3CA and VHL, although with no correlation with treatment response. Among the 15 cytokines evaluated, CXCL9 and LAG-3 levels were significantly different between patients with objective response (OR), stable disease (SD), and progressive disease (PD) following ATZ + BV treatment. Receiver-operating characteristic curve analyses of CXCL9 (cut-off value: 419.1 pg/ml) and LAG-3 (cut-off value: 3736.3 pg/ml) indicated areas of 0.779 and 0.697, respectively, for differentiating PD from non-PD and OR from non-OR. In multivariate analysis of progression-free survival (PFS) and overall survival (OS), high serum CXCL9 (hazard ratio (HR) and 95% confidence interval (CI): 0.412 (0.251-0.677) (p = 0.0005) for PFS and 0.252 (0.125-0.508) (p = 0.0001) for OS), and low serum LAG-3 (HR and 95% CI 0.419 (0.249-0.705) (p = 0.0011) for PFS and 0.294 (0.140-0.617) (p = 0.0012) for OS) were independent positive predictive factors., Conclusion: Although, as far as we examined, no ctDNA mutations in blood were found to be related to ATZ + BV treatment efficacy, serum CXCL9 and LAG-3 levels, which are related to the cancer-immune cycle, were associated with treatment efficacy and could be predictive markers of the efficacy of ATZ + BV treatment in HCC patients., (© 2024.

- Abstract
The mesothelium is a non-adhesive protective surface that lines the serosal cavities and organs within the body. The glycocalyx is a complex structure that coats the outer layer of the mesothelium. However, due to the limitations of conventional fixation techniques, studies on glycans are limited. In this study, lectin staining of frozen tissues was performed to investigate the diversity of glycans in the glycocalyx of mesothelial cells in mice. Datura stramonium lectin (DSL), which recognizes lactosamine and binds to Galectin-3 and -1, was broadly bound to the mesothelial cells of the visceral and parietal peritoneum but not to the pancreas, liver, intestine, or heart. Furthermore, human mesothelial cells in the omentum and parietal peritoneum were positive for DSL. Erythrina cristagalli lectin binding was specific to mesothelial cells in the parietal peritoneum, that is, the pleura, diaphragm, and peritoneum. Intriguingly, surface sialylation, the key element in reducing peritoneal dissemination and implantation, and promoting ascites formation by ovarian carcinoma cells, was much higher in the parietal peritoneum than in the omentum. These findings revealed slight differences in the glycans of mesothelial cells of different organs, which may be related to clinical diseases. These results also suggest that there may be differences in the functions of parietal and visceral mesothelial cells., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

- Abstract
Background: To evaluate esophageal varices (EVs) as predictors of poor prognosis with low tolerability after balloon-occluded retrograde transvenous obliteration (BRTO) in patients with overt hepatic encephalopathy (HE)., Methods: This study retrospectively enrolled 107 patients who underwent BRTO for uncontrollable overt HE. The enrolled patients were divided into two groups based on the presence of EVs using propensity matching. The present study assessed the technical success rate and safety of BRTO in both the groups. Further, the event-free survival, HE-free survival, and the overall survival (OS) were compared between the two groups. Event-free survival was defined as the time period during which the patients did not developed complications related to portal hypertension, including EVs, hepatic ascites, and portal vein thrombosis., Results: After propensity matching, the EV and non-EV groups had 37 and 36 patients, respectively. Only one patient experienced an unsuccessful procedure in the EV group. Procedure-related adverse events in the EV group and non-EV group occurred in 11 and 7 patients, respectively. (P=0.417) The event free survival after BRTO in the EV and non-EV group were 1,283 (95% CI: 798 - 1,767) days and 2,257 (1,722-2,792) days, respectively. Event free survival was significantly worse in the EV group than in the non-EV group (P=0.014). Furthermore, the EV group experienced worse OS than the non-EV group (P=0.001 and P<0.001, respectively)., Conclusions: The presence of EVs could potentially be associated with a higher risk of adverse outcomes or mortality after BRTO treatment in individuals with HE., (The Author(s).

- Abstract
Study Design: Retrospective comparative study., Objectives: This study aimed to determine whether the severity of preoperative gait disturbance remains after surgical resection in patients with intramedullary spinal cord tumors (IMSCTs), and to identify any factors influencing poor improvement in postoperative gait disturbance., Methods: The study included a total of 128 patients with IMSCTs requiring surgical excision between 2006 and 2019. Based on the degree of preoperative gait disturbance assessed by the modified McCormick scale (MMCS) grade, patients were categorized into Mild (I-II) and Severe (III-V) groups. The mean postoperative follow-up period was 55.5 ± 34.3 months, and demographic and surgical characteristics were compared between the two groups., Results: Significant differences were observed in age at surgery, tumor location, tumor size, estimated blood loss, intraoperative motor-evoked potential disappearance, extent of resection, and tumor histopathology between the Mild and Severe groups. In the Mild group, at the final follow-up, only 7.3% of patients experienced improvement, 56.0% showed no changes, and 36.7% experienced deterioration. Conversely, in the Severe group, 26.3% of patients experienced improvement, 31.6% showed no changes, and 42.1% experienced deterioration. Tumor location and age at surgery were identified as factors correlated with poor improvement in postoperative gait disturbance in the Mild group., Conclusions: Irrespective of the preoperative gait disturbance degree, approximately 40% of patients with IMSCTs experienced deterioration in gait after tumor resection. For preoperative MMCS grade I-II cases, older age at surgery and thoracic IMSCTs would be important factors associated with poor improvement in postoperative gait disturbance., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background: Internal carotid artery (ICA) dissection is a relatively rare cause of acute ischemic stroke. Stretching and compression of ICA due to sudden acceleration, deceleration, and rotational forces are risk factors for ICA dissection. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is believed to trigger an inflammatory response that exacerbates endothelial dysfunction and leads to arterial dissection. Although levodopa-induced cervical dyskinesia in Parkinson's disease often manifests as choreiform movement, dissection has not been reported in such patients., Case Presentation: A 51-year-old man with Parkinson's disease (PD) presented with gradually worsening neck pain and transient aphasia 1 week after mild coronavirus disease 2019 (COVID-19) infection. The patient already had neck pain due to cervical spondylosis and presented with levodopa-induced cervical dyskinesia. Magnetic resonance imaging revealed acute ischemic stroke in the left parietal lobe and an intramural hematoma with an area of stenosis in the left ICA. The patient was diagnosed with left ICA dissection., Conclusions: COVID-19 infection can cause vessel wall vulnerability. Although patients with PD often have neck pain, ICA dissection should be considered a differential diagnosis if the patient has a recent history of COVID-19., Competing Interests: The authors declare that they have no conflict of interest., (© 2024 The Authors.

- Abstract
Alcohol-associated liver disease (ALD), including alcoholic fatty liver, is a serious problem in many countries, and its economic costs to society are enormous. There is evidence indicating the relations between gut environments and liver disease, and thus, improvement of gut environment is expected to be an effective approach for ALD prevention. In this study, we explored the preventive effect of partially hydrolyzed guar gum (PHGG) on ALD focusing on the gut-liver axis. Two weeks of PHGG pre-feeding suppressed the liver fat accumulation in the experimental binge alcohol model mouse. In cecal microbiome, PHGG pre-feeding increased beneficial Bifidobacterium with its metabolite acetate concentration and suppressed the alcohol-induced increase in the potential pathobiont Streptococcus. PHGG pre-feeding increased colonic gene expression of angiogenin genes, which act as antimicrobial peptides and decreased expression of genes for mast cell protease, which suggests a potential involvement in leaky gut. Correlation network analysis based on evaluated parameters revealed four relations worth noticing. (i) The abundance of Bifidobacterium positively correlated with cecal acetate. (ii) Cecal acetate negatively correlated with Streptococcus via colonic angiogenin expression. (iii) Streptococcus positively correlated with liver fat area. (iv) Cecal acetate had direct negative correlation with liver fat area. Considering these relations comprehensively, acetate produced by Bifidobacterium may be a key mediator in ALD prevention; it inhibited growth of potential pathobiont Streptococcus and also directly regulated liver lipid metabolism reaching through portal vein. This study demonstrated that regularly intake of PHGG may be effective in reducing the risk of alcoholic fatty liver via gut-liver axis., (© 2024 The Author(s).

- Abstract
Study Design: Retrospective multicenter study., Objectives: To evaluate how preoperative neck pain influences clinical outcomes following posterior decompression for cervical ossification of the posterior longitudinal ligament (OPLL)., Setting: Fourteen medical institutions in Japan., Methods: We enrolled 90 patients with cervical OPLL who underwent posterior decompression and were followed for a minimum of two years. We collected demographic data, medical history, and imaging findings. Patients were divided into two groups based on preoperative neck pain presence (Pre-op. neck pain (-) and (+) groups), and their outcomes were compared., Results: There were no significant differences in patient demographics between the Pre-op. neck pain (-) and (+) groups. Both groups showed similar distributions of ossification types and K-line positivity. Perioperative complications were comparable between the two groups. Radiographic analysis revealed no significant differences in C2-7 angles or cervical range of motion, pre- and postoperatively. Both groups demonstrated significant improvement in postoperative Japanese orthopedic association (JOA) scores, but there were no significant differences in scores or recovery rates. In the Pre-op. neck pain (-) group, factors associated with appearance of postoperative neck pain included pre- and postoperative lower JOA scores and larger C2-7 angles in neutral and extension positions., Conclusions: It emerges that lower pre- and postoperative JOA scores or larger C2-7 angles in neutral and extension positions predispose to postoperative neck pain even in those patients without preoperative neck pain. Therefore, this is worth discussing at the time of consenting patients for surgical decompression and fixation., (© 2024. The Author(s), under exclusive licence to International Spinal Cord Society.)

- Abstract
A down-flow hanging sponge (DHS) reactor is a trickling filter system used for wastewater treatment, which employs sponges to retain biomass. This study assessed the process performance of a compact DHS combined with a sedimentation tank with seven phases at varying hydraulic retention times (HRT) over 500 days. The BOD of the DHS effluent was maintained at 4.0 ± 0.5 mg·L
-1 for the shortest HRT 0.3 ± 0.1 h. The nitrification efficiency was considerably impacted by the reduced HRT, with NH4 + -N and NO3 - -N concentrations of 9.0 ± 1.2 mgN·L-1 and 2.2 ± 0.5 mgN·L-1 , respectively. Nevertheless, the effluent complied with effluent discharge standards throughout the trial period. The number of comammox 16S rRNA gene copies ranged from 5.58 to 13.2 × 107 copies·mL-1 , indicating that sponges biomass retained carrier can provide favorable conditions for comammox growth and could contribute to nitrification in the high-rate DHS reactor., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

- Abstract
Rhabdomyolysis can lead to acute kidney injury (AKI), primarily due to myoglobin-induced tubular damage. We present a case of slowly progressive rhabdomyolysis following SARS-CoV-2 infection in a 28-year-old male who was monitored through serial serum creatine kinase (CK) and myoglobin levels. Despite prominent CK elevations, the patient did not develop AKI, probably due to disproportionately mild serum myoglobin elevation with distinctive cyclic spikes. This case underscores the informative value of frequent monitoring of both CK and myoglobin to assess muscle damage severity and AKI risk in rhabdomyolysis, particularly with viral infections like COVID-19 that can cause delayed-onset muscle injury., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

- Abstract
Dye-containing polymers P1 (PEDPP-OT-BDT) and P2 (PEDPP-OT-BDTT) including a π-extended diketopyropyrrole (DPP) derivative and electron-rich thiophene fused ring units (4,8-bis((2-ethylhexyl)oxy)benzo[1,2-b:4,5-b']dithiophene for P1 and 4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b']dithiophene for P2) were synthesized as narrow band gap dyes. A π-extended DPP (EDPP-OT-BrPh), fragment of the polymers P1 and P2, was obtained by extending the π-conjugation of DPP using Ru(III)-catalyzed C-H and N-H activation reported by Gońka et al. in 2019, exhibiting a high quantum yield (ϕ
em =0.84) and small HOMO-LUMO gap (Eg =1.69 eV) due to the spatial overlap of the HOMO and LUMO orbitals. The solubility of the π-extended DPP was improved by introducing four 2-octylthophene side chains around the periphery of the planer dye moiety, while maintaining the high planarity of the dye molecule, which is essential to the function of optoelectronic devices. As a result, P1 and P2, polymerized with the π-extended DPP and BDT derivatives, exhibit carrier mobility of approximately 10-5 cm2 /Vs in organic field-effect transistors (OFETs). In bulk heterojunction (BHJ) solar cells with [6,6]-phenyl-C61 -butyric acid methyl ester (PCBM), they demonstrate a power conversion efficiency (PCE) of 1.0 % with an average transmittance (AVTs) of around 60 %., (© 2024 Wiley-VCH GmbH.)- Published

- Abstract
To understand why Chlamydia trachomatis (Ct) (L2/434/Bu) favors hypoxia, we examined the dynamics of infected cells using a glycolysis-related PCR array and metabolomic analysis, along with the perturbation of nucleotide synthesis. Our findings revealed that, compared to normoxia, hypoxia with infection significantly and selectively upregulates the expression of genes related to glycolysis, glycogen degradation, and the pentose phosphate pathway. Furthermore, hypoxia induced a significant decrease in metabolite levels, particularly methionine-related metabolites, independent of infection, indicating efficient metabolism under hypoxia. Additionally, the perturbation of nucleotide synthesis with adenosine derivatives impaired Ct growth. Collectively, our results suggest that Ct favors a hypoxic environment with efficient metabolism, in which Ct readily activates glycolysis responsible for stable nucleotide synthesis as well as ATP supply., Competing Interests: Declaration of competing interest We have no conflicts of interest in association with the present study., (Copyright © 2024 Elsevier Inc.

- Abstract
Prolonged positive polymerase chain reaction (PCR) results, irrespective of the transmission risk, can lead to prolonged restrictions on daily activities and infection precaution interventions. Studies evaluating the duration of PCR positivity for multiple pathogens in a single patient cohort are scarce. This study aimed to evaluate and compare the durations of PCR positivity for multiple respiratory viruses among children and adolescents. This retrospective study was conducted between April 2018 and March 2024 using a multiplex PCR respiratory panel for symptomatic children and adolescents who had at least two tests within 90 days of study period, with the first PCR test positive. The rate and likelihood of persistent PCR positivity were evaluated for multiple respiratory viruses. For 1325 positive results, repeat tests were conducted within 90 days. The persistent PCR positivity rate at repeat testing decreased over time (60.6%, Days 1-15 and 21.7%, Days 76-90, after the first test). In multivariate logistic regression analysis, an increased likelihood of persistent PCR positivity was observed for rhinovirus/enterovirus and adenovirus, whereas decreased likelihood of persistent positivity was seen in influenza and seasonal coronaviruses, compared with parainfluenza viruses. Persistent PCR positivity is common for multiple respiratory viruses in symptomatic children., (© 2024 Wiley Periodicals LLC.)

- Abstract
This study aimed to complement the results of the REACH-2 study by prospectively evaluating the safety and efficacy of ramucirumab in advanced hepatocellular carcinoma (HCC) in a real-world setting. This was an open-label, nonrandomized, multicenter, prospective study conducted at 13 institutions in Japan (jRCTs031190236). The study included Child-Pugh Class A patients with advanced HCC who had received pretreatment with atezolizumab plus bevacizumab (Atez/Bev) or lenvatinib. Ramucirumab was introduced as a second-line treatment after Atez/Bev or lenvatinib and as a third-line treatment after Atez/Bev and lenvatinib. Between May 2020 and July 2022, we enrolled 19 patients, including 17 who received ramucirumab. Additionally, seven patients received lenvatinib, another seven patients received Atez/Bev, and three patients received Atez/Bev followed by lenvatinib as prior treatment. The primary endpoint was a 6-month progression-free survival (PFS) rate, which was 14.3%. The median PFS and overall survival were 3.7 and 12.0 months, respectively. The most common grade ≥ 3 adverse events (AEs) were hypertension (23.5%), proteinuria (17.6%), and neutropenia (11.8%). The discontinuation rate due to AEs was 29.4%. Six patients progressed from Child-Pugh A to B after treatment with ramucirumab. Thirteen patients were eligible for post-ramucirumab treatment, including systemic therapy. Despite the limited number of patients, the efficacy of ramucirumab was comparable to that observed in the REACH-2 study when used after lenvatinib and Atez/Bev. However, the incidence of AEs was higher than that in the REACH-2 study., (© 2024. The Author(s).)

- Abstract
Background: This study aimed to clarify the morphological changes in esophageal varices after achieving sustained virological response (SVR) with direct-acting antivirals (DAAs) in patients with cirrhosis., Methods: A total of 243 patients underwent esophagogastroduodenoscopy before DAA treatment and after achieving SVR. Morphological changes in esophageal varices were investigated using esophagogastroduodenoscopy., Results: This study comprised 125 males and 118 females with a median age of 68 years. Esophageal varices at baseline were classified into no varix in 155 (63.8%), F1 in 59 (24.3%), F2 in 25 (10.3%) and F3 in 4 (1.6%) patients. The improvement, unchanged, and aggravation rates of esophageal varices after SVR were 11.9%, 73.3%, and 14.8%, respectively. High ALBI score at SVR12 was an independent factor associated with post-SVR esophageal varices aggravation (p = 0.045). Time-dependent receiver operating characteristic (ROC) curve analysis revealed a cut-off value of - 2.33 for ALBI score at SVR12 in predicting post-SVR esophageal varices aggravation. Of the 155 patients without esophageal varices at baseline, 17 developed de novo post-SVR esophageal varices. High ALBI score at SVR12 was a significant independent factor associated with de novo post-SVR esophageal varices (p = 0.046). ROC curve analysis revealed a cut-off value of - 2.65 for ALBI score at SVR12 in predicting de novo post-SVR esophageal varices., Conclusions: Patients with cirrhosis can experience esophageal varices aggravation or de novo esophageal varices, despite achieving SVR. In particular, patients with high ALBI score at SVR12 have a high likelihood of developing post-SVR esophageal varices aggravation or de novo post-SVR esophageal varices., (© 2024.

- Abstract
Study Design: Retrospective comparative study., Objective: To evaluate the relationship between pelvic incidence (PI) and proximal junctional kyphosis (PJK) in patients with Lenke type 5 adolescent idiopathic scoliosis (AIS)., Summary of Background Data: Although PJK is a common complication of sagittal malalignment after posterior correction and fusion surgery (PSF), few studies have assessed its risk factors. The significance of pelvic morphology in relation to PJK has been suggested but remains unclear in Lenke type 5 AIS patients., Methods: A total of 92 patients with Lenke type 5 AIS who underwent selective thoracolumbar PSF with a minimum follow-up of two years were included. Patients were divided into PJK and non-PJK groups based on postoperative radiographs. The influence of PI on PJK occurrence was evaluated through binary logistic analysis. Subgroup analysis was performed based on the PI value (low PI,<45°; high PI, ≥ 45°) to identify factors affecting PJK occurrence., Results: PJK was observed in 17.4% of the whole cohort. Binary logistic regression analysis identified low PI and large TL/L curve as a risk factor for PJK (PI, odds ratio, 0.933; TL/L curve, odds ratio, 1.080). Subgroup analysis showed that the postoperative increase in the upper instrumented vertebra slope in PJK cases was comparable in both the low and high PI groups. Meanwhile, lordotic changes in the fused area in the PJK cases were observed only in the low PI group. No difference in the Scoliosis Research Society 22 scores were observed between the two groups., Conclusion: From this study a low PI was identified as a risk factor for the occurrence of PJK in Lenke type 5 AIS patients. The occurrence of PJK is influenced by lordotic changes in the fused area and the limited compensatory capacity of the pelvis in patients with a low PI., Competing Interests: Conflict of interest disclosure: There is no financial conflict of interest to disclose in relation to this work, (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Background and Aims: As practice patterns and hepatitis C virus (HCV) genotypes (GT) vary geographically, a global real-world study from both East and West covering all GTs can help inform practice policy toward the 2030 HCV elimination goal. This study aimed to assess the effectiveness and tolerability of DAA treatment in routine clinical practice in a multinational cohort for patients infected with all HCV GTs, focusing on GT3 and GT6., Methods: We analyzed the sustained virological response (SVR12) of 15,849 chronic hepatitis C patients from 39 Real-World Evidence from the Asia Liver Consortium for HCV clinical sites in Asia Pacific, North America, and Europe between 07/01/2014-07/01/2021., Results: The mean age was 62±13 years, with 49.6% male. The demographic breakdown was 91.1% Asian (52.9% Japanese, 25.7% Chinese/Taiwanese, 5.4% Korean, 3.3% Malaysian, and 2.9% Vietnamese), 6.4% White, 1.3% Hispanic/Latino, and 1% Black/African-American. Additionally, 34.8% had cirrhosis, 8.6% had hepatocellular carcinoma (HCC), and 24.9% were treatment-experienced (20.7% with interferon, 4.3% with direct-acting antivirals). The largest group was GT1 (10,246 [64.6%]), followed by GT2 (3,686 [23.2%]), GT3 (1,151 [7.2%]), GT6 (457 [2.8%]), GT4 (47 [0.3%]), GT5 (1 [0.006%]), and untyped GTs (261 [1.6%]). The overall SVR12 was 96.9%, with rates over 95% for GT1/2/3/6 but 91.5% for GT4. SVR12 for GT3 was 95.1% overall, 98.2% for GT3a, and 94.0% for GT3b. SVR12 was 98.3% overall for GT6, lower for patients with cirrhosis and treatment-experienced (TE) (93.8%) but ≥97.5% for treatment-naive patients regardless of cirrhosis status. On multivariable analysis, advanced age, prior treatment failure, cirrhosis, active HCC, and GT3/4 were independent predictors of lower SVR12, while being Asian was a significant predictor of achieving SVR12., Conclusions: In this diverse multinational real-world cohort of patients with various GTs, the overall cure rate was 96.9%, despite large numbers of patients with cirrhosis, HCC, TE, and GT3/6. SVR12 for GT3/6 with cirrhosis and TE was lower but still excellent (>91%)., Competing Interests: FJ: Speaker fees: Gilead Sciences, MSD, and Ascletis. Consultancy: Gilead Sciences, MSD.

- Abstract
Study Design: Retrospective case series., Objective: The aim of this study was to compare the outcomes of posterior decompression surgery for lumbar spinal canal stenosis (LSS) in patients with preoperative sagittal malalignment (MA) with those without, after adjusting for age and sex., Summary of Background Data: Sagittal balance is an important factor in spine surgery and is thought to affect postoperative outcomes after LSS. However, the relationship between sagittal MA and postoperative outcomes has not been thoroughly examined., Patients and Methods: We included 533 patients who underwent surgical treatment for LSS and also achieved 2-year follow-up. Patients were categorized into either an MA+ group (69 patients) or a matched-alignment (MA-) group (348 patients) based on age-adjusted preoperative sagittal alignment. We compared the baseline and 2-year postoperative health-related quality of life (HRQOL) using the Visual Analog Scale and Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ) scores. We also calculated clinical efficacy using the minimal clinically important difference based on JOABPEQ scores, and age and sex-adjusted JOABPEQ scores 2 years after surgery. Differences between groups were examined using the Mann-Whitney U test and χ 2 analysis, where applicable., Results: Both groups showed an improved HRQOL after decompression surgery. Similar proportions of patients showed substantial improvement, as estimated by the minimal clinically important difference, in 4 out of 5 subdomains of the JOABPEQ. A significantly smaller proportion of patients in the MA+ group showed substantial improvement in lumbar function. The age and sex-adjusted HRQOL scores 2 years after surgery were lower in the MA+ group, particularly in the lumbar function and social life function subdomains of the JOABPEQ., Conclusion: The effects of posterior decompression surgery alone can still be observed at least 2 years postoperatively for patients with LSS and concomitant sagittal MA. Patients with sagittal MA may experience lower HRQOL than those without this type of MA., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

- Abstract
Continuous intravenous adenosine triphosphate (ATP) administration is the standard method for inducing maximal hyperemia in fractional flow reserve (FFR) measurements. Several cases have demonstrated fluctuations in the ratio of mean distal coronary pressure to mean arterial pressure (Pd/Pa) value during ATP infusion, which raised our suspicions of FFR value inaccuracy. This study aimed to investigate our hypothesis that Pd/Pa fluctuations may indicate inaccurate FFR measurements caused by insufficient hyperemia. We examined 57 consecutive patients with angiographically intermediate coronary lesions who underwent fractional flow reverse (FFR) measurements in our hospital between November 2016 and September 2018. Pd/Pa was measured after continuous ATP administration (150 μg/kg/min) via a peripheral forearm vein for 5 min (FFR
A ); and we analyzed the FFR value variation in the final 20 s of the 5 min, defining 'Fluctuation' as variation range > 0.03. Then, 2 mg of nicorandil was administered into the coronary artery during continued ATP infusion, and the Pd/Pa was remeasured (FFRA+N ). Fluctuations were observed in 23 of 57 patients. The cases demonstrating discrepancies of > 0.05 between FFRA and FFRA+N were observed more frequently in the fluctuation group than in the non-fluctuation group (12/23 vs. 1/34; p < 0.0001). The discrepancy between FFRA and FFRA+N values was smaller in the non-fluctuation group (mean difference ± SD; -0.00026 ± 0.04636 vs. 0.02608 ± 0.1316). Pd/Pa fluctuation with continuous ATP administration could indicate inaccurate FFR measurements caused by incomplete hyperemia. Additional vasodilator administration may achieve further hyperemia when Pd/Pa fluctuations are observed., (© 2024. Springer Nature Japan KK, part of Springer Nature.)- Published

- Abstract
Background: Atezolizumab plus bevacizumab (Atezo/Bev) is frequently selected as the primary systemic therapy for hepatocellular carcinoma (HCC)., Aims: To investigate the outcomes of patients with HCC treated with Atezo/Bev in a real-world setting based on whether they met the inclusion criteria for the phase 3 IMbrave150 trial., Methods: A total of 936 patients were enrolled. There were 404 patients who met the inclusion criteria of the phase 3 IMbrave150 trial (IMbrave150 group) and 532 who did not (non-IMbrave150 group)., Results: Median progression-free survival (PFS) in the IMbrave150 and non-IMbrave150 groups was 7.4 months and 5.6 months (p = 0.002). Multivariable analysis revealed that non-B, non-C HCC aetiology (hazard ratio [HR], 1.173), α-fetoprotein ≥100 ng/mL (HR, 1.472), Barcelona Clinic Liver Cancer stage ≥ C (HR, 1.318), and modified albumin-bilirubin (mALBI) grade 2b or 3 (HR, 1.476) are independently associated with PFS. Median overall survival (OS) in the IMbrave150 and non-Imbrave150 groups was 26.5 and 18.8 months (p < 0.001). Multivariable analysis revealed that Eastern Cooperative Oncology Group performance status ≥2 (HR, 1.986), α-fetoprotein ≥100 ng/mL (HR, 1.481), and mALBI grade 2b or 3 (HR, 2.037) are independently associated with OS. In subgroup analysis, there were no significant differences in PFS or OS between these groups among patients with mALBI grade 1 or 2a., Conclusions: Patients who are treated with Atezo/Bev and meet the inclusion criteria for the phase 3 IMbrave150 trial, as well as those who do not meet the inclusion criteria but have good liver function, have a good prognosis for survival., (© 2024 John Wiley & Sons Ltd.)

- Abstract
Research Question: How, and to what extent, do anticentromere antibodies (ACA) reduce live birth outcomes after ICSI?, Study Design: Retrospective cohort study of infertile women aged 30-43 years who underwent ICSI between September 2016 and March 2021. Women with a history or current diagnosis of symptomatic connective tissue disease were excluded. Immunofluorescence staining detected antinuclear antibodies (ANA). Staining pattern and titre (cut-off, 1:160) were used to divide infertile women into three groups: positive for ACA (ACA+) (n = 28); positive for ANA other than ACA (ANA+) (n = 77); and negative for both ACA and ANA (control) (n = 3723)., Results: Cumulative live birth rate (CLB) was lowest in ACA+ (7%, 31% and 46% in ACA+, ANA+ and control, respectively) (ACA+ versus control, P < 0.0001; ACA+ versus ANA+, P = 0.011; ANA+ versus control, P = 0.012). A small impairment in meiosis I and a larger impairment in meiosis II, fertilization and embryo cleavage caused the decrease. Multiple pronuclei formation increased (RR versus control, 5.33; 95% CI 4.26 to 6.65) and good-quality blastocyst development decreased (RR 0.34; 95% CI 0.22 to 0.53). Multiple logistic regression analysis showed that ACA was associated with CLB outcome (OR 0.08, 95% CI 0.02 to 0.36); the other four ANA staining patterns were not., Conclusions: The effect of ACA on live birth outcomes is strongest after ICSI among ANA, primarily through the impairment of meiosis II and subsequent stages. Repeated ICSI failure and eggs with multiple pronuclei may warrant specific testing for ACA., (Copyright © 2024 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Background: In the context of patients with hepatocellular carcinoma (HCC) treated with systemic therapy, the correlation between the appearance of adverse events (AEs) and reported efficacy outcomes is well-known and widely investigated. From other pathological settings, we are aware of the prognostic and predictive value of the occurrence of immune-related AEs in patients treated with immune-checkpoint inhibitors., Objective: This retrospective multicenter real-world study aims to investigate the potential prognostic value of AEs in patients with HCC treated with atezolizumab plus bevacizumab in the first-line setting., Patients and Methods: The study population consisted of 823 patients from five countries (Italy, Germany, Portugal, Japan, and the Republic of Korea)., Results: Of the patients, 73.3% presented at least one AE during the study period. The most common AEs were proteinuria (29.6%), arterial hypertension (27.2%), and fatigue (26.0%). In all, 17.3% of the AEs were grade (G) 3. One death due to bleeding was reported. The multivariate analysis confirmed the appearance of decreased appetite G < 2 [versus G ≥ 2; hazard ratio (HR) 0.60; 95% confidence interval (CI) 0.13-0.90; p < 0.01] and immunotoxicity G < 2 (versus G ≥ 2; HR: 0.70; 95% CI 0.24-0.99; p = 0.04) as independent prognostic factors for overall survival, and the appearance of decreased appetite G < 2 (versus G ≥ 2; HR: 0.73; 95% CI 0.43-0.95; p = 0.01), diarrhea (yes versus no; HR: 0.57, 95% CI 0.38-0.85; p = 0.01), fatigue (yes versus no; HR: 0.82, 95% CI 0.65-0.95; p < 0.01), arterial hypertension G < 2 (versus G ≥ 2; HR: 0.68, 95% CI 0.52-0.87; p < 0.01), and proteinuria (yes versus no; HR: 0.79, 95% CI 0.64-0.98; p = 0.03) as independent prognostic factors for progression-free survival., Conclusions: As demonstrated for other therapies, there is also a correlation between the occurrence of AEs and outcomes for patients with HCC for the combination of atezolizumab plus bevacizumab., (© 2024.

- Abstract
Background: Because apolipoprotein-A2 (ApoA2), a key component of high-density lipoprotein cholesterol (HDL-C), lacks clear clinical significance, we investigated its impact on cardiovascular events in patients undergoing percutaneous coronary intervention (PCI).Methods and Results: We examined 638 patients who underwent PCI with a new-generation drug-eluting stent for acute or chronic coronary syndrome and had their apolipoprotein levels measured between 2016 and 2021. The patients were divided into 2 groups based on the median serum ApoA2 values, and the incidence of major adverse cardiovascular events (MACE) was assessed. Of the 638 patients, 563 (88%) received statin treatment, with a median serum LDL-C level of 93 mg/dL. Furthermore, 137 patients (21.5%) experienced MACE, and Kaplan-Meier analysis revealed that the higher ApoA2 group had a significantly lower incidence of MACE than the lower ApoA2 group (30.9% vs. 41.6%). However, the other apolipoproteins, including ApoA1, ApoB, ApoC2, ApoC3, and ApoE, showed no significant differences in MACE. Multivariable Cox hazard analysis indicated that ApoA2 was an independent predictor of MACEs (hazard ratio, 0.666; 95% confidence interval, 0.465-0.954). Furthermore, ApoA2 levels exhibited the strongest inverse association with high-sensitivity C-reactive protein levels (r
s =-0.479)., Conclusions: Among all the apolipoproteins, the serum ApoA2 level may be the strongest predictor of future cardiovascular events and prognosis in patients undergoing PCI.- Published

- Abstract
Study Design: Retrospective multicenter study., Objectives: To investigate surgical outcomes following posterior decompression for cervical ossification of the posterior longitudinal ligament (OPLL) when performed by board-certified spine (BCS) or non-BCS (NBCS) surgeons., Methods: We included 203 patients with cervical OPLL who were followed for a minimum of 1 year after surgery. Demographic information, medical history, and imaging findings were collected. Clinical outcomes were assessed preoperatively and at the final follow-up using the Japanese Orthopedic Association (JOA) score and the visual analog scale (VAS) for the neck. We compared outcomes between BCS surgeons, who must meet several requirements, including experience in more than 300 spinal surgeries, and NBCS surgeons., Results: BCS surgeons performed 124 out of 203 cases, while NBCS surgeons were primary in 79 cases, with 73.4% were directly supervised by a BCS surgeon. There was no statistically significant difference in surgical duration, estimated blood loss, and perioperative complication rates between the BCS and NBCS groups. Moreover, no statistically significant group differences were observed in each position of the C2-7 angle and cervical range of motion at preoperation and the final follow-up. Preoperative and final follow-up JOA scores, VAS for the neck, and JOA score recovery rate were comparable between the two groups., Conclusions: Surgical outcomes, including functional recovery, complication rates, and cervical dynamics, were comparable between the BCS and NBCS groups. Consequently, posterior decompression for cervical OPLL is considered safe and effective when conducted by junior surgeons who have undergone training and supervision by experienced spine surgeons., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Purpose: There have been numerous studies focused on the stiffness of tracheal cartilage. However, no research has been conducted specifically on the annular ligament, nor have any regional differences in the annular ligament been identified. The purpose of this study was to investigate the stiffness of the ligaments present between the thyroid, cricoid and tracheal cartilages., Methods: The ligaments were identified in the cervical region of living subjects with ultrasonography. The stiffness of the ligaments was measured from the body surface using a digital palpation device (MyotonPRO). Since it is impossible to measure the entire trachea in a living subject, an additional measurement was performed on human cadavers., Results: Both in vivo and cadaveric investigations found that the stiffness of annular ligaments decreased gradually from the superior to inferior parts. There was no difference in the stiffness between males and females in the superior part of the trachea. However, the stiffness of the middle and inferior parts was predominantly higher in females than in males. Furthermore, males showed significant differences in stiffness between the superior and middle parts, while females showed no significant differences., Conclusion: These results reveal that there are regional and sex-related differences in the stiffness of human tracheal ligaments., (© 2024.

- Abstract
Oxaliplatin, a platinum-based anticancer drug, is associated with peripheral neuropathy (oxaliplatin-induced peripheral neuropathy, OIPN), which can lead to worsening of quality of life and treatment interruption. The endothelial glycocalyx, a fragile carbohydrate-rich layer covering the luminal surface of endothelial cells, acts as an endothelial gatekeeper and has been suggested to protect nerves, astrocytes, and other cells from toxins and substances released from the capillary vessels. Mechanisms underlying OIPN and the role of the glycocalyx remain unclear. This study aimed to define changes in the three-dimensional ultrastructure of capillary endothelial glycocalyx near nerve fibers in the hind paws of mice with OIPN. The mouse model of OPIN revealed disruption of the endothelial glycocalyx in the peripheral nerve compartment, accompanied by vascular permeability, edema, and damage to the peripheral nerves. To investigate the potential treatment interventions, nafamostat mesilate, a glycocalyx protective agent was used in tumor-bearing male mice. Nafamostat mesilate suppressed mechanical allodynia associated with neuropathy. It also prevented intra-epidermal nerve fiber loss and improved vascular permeability in the peripheral paws. The disruption of endothelial glycocalyx in the capillaries that lie within peripheral nerve bundles is a novel finding in OPIN. Furthermore, these findings point toward the potential of a new treatment strategy targeting endothelial glycocalyx to prevent vascular injury as an effective treatment of neuropathy as well as of many other diseases. PERSPECTIVE: OIPN damages the endothelial glycocalyx in the peripheral capillaries, increasing vascular permeability. In order to prevent OIPN, this work offers a novel therapy approach that targets endothelial glycocalyx., (Copyright © 2024 United States Association for the Study of Pain, Inc.

- Abstract
Background: The integration of artificial intelligence (AI), particularly deep learning models, has transformed the landscape of medical technology, especially in the field of diagnosis using imaging and physiological data. In otolaryngology, AI has shown promise in image classification for middle ear diseases. However, existing models often lack patient-specific data and clinical context, limiting their universal applicability. The emergence of GPT-4 Vision (GPT-4V) has enabled a multimodal diagnostic approach, integrating language processing with image analysis., Objective: In this study, we investigated the effectiveness of GPT-4V in diagnosing middle ear diseases by integrating patient-specific data with otoscopic images of the tympanic membrane., Methods: The design of this study was divided into two phases: (1) establishing a model with appropriate prompts and (2) validating the ability of the optimal prompt model to classify images. In total, 305 otoscopic images of 4 middle ear diseases (acute otitis media, middle ear cholesteatoma, chronic otitis media, and otitis media with effusion) were obtained from patients who visited Shinshu University or Jichi Medical University between April 2010 and December 2023. The optimized GPT-4V settings were established using prompts and patients' data, and the model created with the optimal prompt was used to verify the diagnostic accuracy of GPT-4V on 190 images. To compare the diagnostic accuracy of GPT-4V with that of physicians, 30 clinicians completed a web-based questionnaire consisting of 190 images., Results: The multimodal AI approach achieved an accuracy of 82.1%, which is superior to that of certified pediatricians at 70.6%, but trailing behind that of otolaryngologists at more than 95%. The model's disease-specific accuracy rates were 89.2% for acute otitis media, 76.5% for chronic otitis media, 79.3% for middle ear cholesteatoma, and 85.7% for otitis media with effusion, which highlights the need for disease-specific optimization. Comparisons with physicians revealed promising results, suggesting the potential of GPT-4V to augment clinical decision-making., Conclusions: Despite its advantages, challenges such as data privacy and ethical considerations must be addressed. Overall, this study underscores the potential of multimodal AI for enhancing diagnostic accuracy and improving patient care in otolaryngology. Further research is warranted to optimize and validate this approach in diverse clinical settings., (©Masao Noda, Hidekane Yoshimura, Takuya Okubo, Ryota Koshu, Yuki Uchiyama, Akihiro Nomura, Makoto Ito, Yutaka Takumi.

- Abstract
Introduction: Overweight is a negative prognostic factor in the general population in the long term. However, the role of body mass index (BMI) in the short-mid term in advanced tumours is unclear. The present analysis investigates the role of BMI weight classes in a large sample of patients affected by HCC and receiving atezolizumab plus bevacizumab or lenvatinib as first-line treatment., Methods and Material: The cohort included consecutive patients affected by BCLC-c and BCLC-B HCC patients from a multicenter international study group who received atezolizumab plus bevacizumab or lenvatinib as first-line therapy. Population was stratified according to the BMI in under-, over- and normal-weight according to the conventional thresholds. The primary objective of the study was to evaluate the prognostic and predictive impact of BMI in patients affected by advanced or intermediate HCC. Survival curves were estimated using the product-limit method of Kaplan-Meier. The role of stratification factors was analysed with log-rank tests., Results: 1292 consecutive patients with HCC were analysed. 466 (36%) patients were treated with lenvatinib and 826 (64%) patients were treated with atezolizumab plus bevacizumab. In the atezolizumab plus bevacizumab arm, 510 (62%) patients were normal-weight, 52 (6%) underweight and 264 (32%) overweight. At the univariate analysis for OS, underweight patients had significantly shorter OS compared to normal-weight patients, whereas no differences were found between normal-weight versus overweight. Multivariate analysis confirmed that underweight patients had significantly shorter OS compared to normal-weight patients (HR: 1.7; 95% CI: 1.0-2.8; p = .0323). In the lenvatinib arm, 26 patients (5.6%) were categorized as underweight, 256 (54.9%) as normal-weight, and 184 (39.5%) as overweight. At the univariate analysis for OS, no significant differences were found between normal-weight versus underweight and between normal-weight versus overweight, which was confirmed at multivariate analysis., Conclusion: Our analysis highlighted a prognostic role of BMI in a cohort of patients with advanced HCC who received atezolizumab plus bevacizumab, while no prognostic role for low BMI was apparent in patients who received lenvatinib., (© 2024 John Wiley & Sons A/S.

- Abstract
Aim: An association between hepatitis B core-related antigen (HBcrAg) kinetics and hepatocarcinogenesis during nucleoside (t)id analog (NA) treatment has recently been reported. HBcrAg kinetics and factors associated with HBcrAg response during tenofovir alafenamide (TAF) administration remain unclear. In this multicenter retrospective study, we aimed to clarify the efficacy and safety of TAF in treatment-naïve patients with chronic hepatitis B, focusing on the reduction in HBcrAg levels., Methods: Patients were treated with TAF monotherapy for 96 weeks, and the kinetics of HBcrAg during treatment and the factors associated with HBcrAg response (defined as a change in HBcrAg of -1 log IU/mL from baseline) were evaluated., Results: The study population comprised 241 patients, 36.9% of whom were HBeAg-positive. The median baseline HBcrAg level was 4.7 log IU/mL. The median change in HBcrAg from baseline was -1.1 log IU/mL at 96 weeks after treatment. The HBcrAg response rate at 96 weeks was 56.6% (43/76). Multivariate analysis revealed high alanine transaminase level as an independent baseline factor associated with HBcrAg response at 96 weeks of treatment (p = 4.53 × 10
-6 ). No correlation was found between the HBcrAg and hepatitis B surface antigen kinetics in patients treated with TAF monotherapy., Conclusions: In TAF monotherapy for patients with chronic hepatitis B, HBcrAg levels were significantly decreased and baseline alanine transaminase level is an important factor associated with HBcrAg reduction. As no correlation was found between HBcrAg and reduced hepatitis B surface antigen levels in this study, HBcrAg kinetics in addition to hepatitis B surface antigen may need to be monitored during TAF treatment., (© 2024 The Authors.

- Abstract
In recent years, several small interfering RNA (siRNA) therapeutics have been approved, and most of them are phosphorothioate (PS)-modified for improving nuclease resistance. This chemical modification induces chirality in the phosphorus atom, leading to the formation of diastereomers. Recent studies have revealed that Sp and Rp configurations of PS modifications of siRNAs have different biological properties, such as nuclease resistance and RNA-induced silencing complex (RISC) loading. These results highlight the importance of determining diastereomeric distribution in quality control. Although various analytical approaches have been used to separate diastereomers (mainly single-stranded oligonucleotides), it becomes more difficult to separate all of them as the number of PS modifications increases. Despite siRNA exhibits efficacy in the double-stranded form, few reports have examined the separation of diastereomers in the double-stranded form. In this study, we investigated the applicability of non-denaturing anion-exchange chromatography (AEX) for the separation of PS-modified siRNA diastereomers. Separation of the four isomers of the two PS bonds tended to improve in the double-stranded form compared to the single-stranded form. In addition, the effects of the analytical conditions and PS-modified position on the separation were evaluated. Moreover, the elution order of the Sp and Rp configurations was confirmed, and the steric difference between them, i.e., the direction of the anionic sulfur atom, appeared to be important for the separation mechanism in non-denaturing AEX. Consequently, all 16 peak tops of the four PS modifications were detected in one sequence, and approximately 30 peak tops were detected out of 64 isomers of six PS bonds, indicating that non-denaturing AEX is a useful technique for the quality control of PS-modified siRNA therapeutics., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

- Abstract
The synthesis of zeolites from two-dimensional layered precursors through interlayer crosslinking of the layers is a promising avenue for realizing meticulously designed synthesis routes. However, the presence of defective silanol species in the precursors hinders the achievement of desirable synthesis outcomes. This study focuses on PREFER-a layered precursor for FER-type zeolites-which was synthesized and subjected to a liquid-mediated defect-healing treatment that we recently developed. The defect-healing process involves the use of fluoride compounds for reconstruction and organic pore fillers to stabilize the framework. The effects of the treatment on the structure, composition, and iron insertion behavior of PREFER were examined. Characterization results revealed a reduction in the number of intralayer silanol defects, whereas interlayer silanols were unaffected by the defect-healing treatment. Furthermore, the subsequent alterations observed in the crosslinking behavior with iron atoms indicated that the defect-healing treatment may enhance the insertion of iron species between the layers in more homogeneous environments compared with the untreated precursor. These findings provide valuable insights into the prospects of controlled interlayer linkage in two-dimensional zeolite materials., Competing Interests: There are no conflicts to declare., (This journal is © The Royal Society of Chemistry.)

- Abstract
In Japan, liver biopsies were previously crucial in evaluating the severity of hepatitis caused by the hepatitis C virus (HCV) and diagnosing HCV-related hepatocellular carcinoma (HCC). However, due to the development of effective antiviral treatments and advanced imaging, the necessity for biopsies has significantly decreased. This change has resulted in fewer chances for diagnosing liver disease, causing many general pathologists to feel less confident in making liver biopsy diagnoses. This article provides a comprehensive overview of the challenges and potential solutions related to liver biopsies in Japan. First, it highlights the importance of considering steatotic liver diseases as independent conditions that can coexist with other liver diseases due to their increasing prevalence. Second, it emphasizes the need to avoid hasty assumptions of HCC in nodular lesions, because clinically diagnosable HCCs are not targets for biopsy. Third, the importance of diagnosing hepatic immune-related adverse events caused by immune checkpoint inhibitors is increasing due to the anticipated widespread use of these drugs. In conclusion, pathologists should be attuned to the changing landscape of liver diseases and approach liver biopsies with care and attention to detail., Competing Interests: Conflict-of-interest statement: The authors declare that they have no conflicts of interest related to this article., (©The Author(s) 2024.

- Abstract
Background: Congenital hearing loss (HL), one of the most common paediatric chronic conditions, significantly affects speech and language development. Its early diagnosis and medical intervention can be achieved via newborn hearing screening. However, data on the prevalence and aetiology of congenital HL in infants who fail newborn hearing screening are limited., Methods: The sample population included 153 913 infants who underwent newborn hearing screening, and the prevalence of congenital HL, defined as moderate to profound bilateral HL (BHL) or unilateral HL (UHL) (≥40 dB HL), in one prefecture of Japan was measured to minimize the loss-to-follow-up rate, a common factor affecting the screening procedure. Comprehensive aetiological investigation, including physiology, imaging, genetic tests, and congenital cytomegalovirus screening, was performed on children diagnosed with congenital HL., Results: The calculated prevalence of congenital HL was 1.62 per 1000 newborns (bilateral, 0.84; unilateral, 0.77). More than half of the cases with congenital bilateral or severe to profound UHL showed genetic aetiology or cochlear nerve deficiency (CND), respectively. Approximately 4% and 6% of the cases of congenital BHL and UHL were associated with congenital cytomegalovirus infection and auditory neuropathy spectrum disorder, respectively., Conclusions: This is an epidemiological and comprehensive aetiological study of congenital HL, as determined via newborn hearing screening according to its severity and laterality, in a large-scale general population of a developed country. Our findings can serve as a reference for optimizing care and intervention options for children with HL and their families., (© The Author(s) 2024.

- Abstract
Introduction: The impact of etiology on response to immunotherapy in advanced hepatocellular carcinoma (HCC) is being debated, with contrasting findings between early and recent post hoc analyses of IMbrave-150 and metanalyses of clinical trials of PD-1/PD-L1 blockers. As a results, it is not clear whether the first-line systemic treatment atezolizumab plus bevacizumab (A + B) is equally effective in viral and nonviral patients., Methods: We retrospectively analyzed 885 HCC patients treated with the first-line A + B from multiple centers from Eastern and Western countries, 53.9% having viral and 46.1% nonviral etiology. Baseline clinical and laboratory characteristics were analyzed with uni- and multivariate models to explore potential differences on overall survival (OS), time-to-progression (TTP), disease control rates (DCRs) based on etiology and to identify putative prognostic factors in etiology subgroups. Treatment toxicities and access to the second-line treatments and outcomes were also reported and compared between etiologies., Results: Overall, no statistically significant differences were found in median OS (mOS: viral 15.9 months; nonviral 16.3 months), TTP (mTTP: viral 8.3 months; nonviral 7.2 months), and DCRs (viral 78.1%; nonviral 80.8%) based on etiology. Prognostic factors of survival and progression were mainly shared between viral and nonviral etiologies, including alpha-fetoprotein, aspartate transaminase, neutrophil-to-lymphocyte ratio (NLR) and ALBI score. Exploratory analyses highlighted a possible stronger association of immunological factors, i.e., NLR and eosinophil count, to treatment outcomes in viral patients. The toxicity profile, the access to and type of the second-line treatments and their outcome in terms of OS almost overlap in the two etiology subgroups., Conclusion: Atezolizumab plus bevacizumab efficacy does not vary according to underlying etiology of HCC in a multicenter, real-world population, matching recent post hoc findings from the IMbrave-150 trial. Preliminary analyses suggest that some prognostic factors differ between viral and nonviral patients, potentially due to biological and immunological differences. Prospective and comparative trials stratifying by etiology are warranted to validate these findings and guide clinical practice., Competing Interests: Andrea Casadei-Gardini has received grants and personal fees from MSD, Eisai, Bayer and is an advisor for MSD, Eisai, Bayer, Bristol-Myers Squibb, AstraZeneca and GSK.

- Abstract
Understanding the effects of lifestyle and radiation on health is important for the health management of disaster recovery workers. International research has demonstrated the relationship between natural disasters and diseases. The lifestyle and working conditions following the Great East Japan Earthquake potentially increased the incidence of cardiovascular disease and obesity among affected individuals. The aim of this study was to analyze the body mass index (BMI) of 1,341 emergency workers who responded to the accident at the Fukushima Daiichi Nuclear Power Plant. The BMI of each emergency worker was measured immediately after the accident and compared with that measured at the initial survey conducted 5 yr later to determine the effect of lifestyle habits on BMI. Awareness of the frequency of eating out and caloric intake helped maintain their BMI, while evacuation contributed to the increase in BMI. Prevention of obesity, which can trigger or exacerbate certain health conditions, such as heat exhaustion, infection, and cerebro-cardiovascular disease, requires diet counseling, with a focus on maintaining adequate caloric intake; moreover, special consideration should be provided to evacuated workers.

- Abstract
Background and Aim: This study aimed to clarify the efficacy and safety of 48-week pemafibrate treatment in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) complicated by dyslipidemia., Methods: A total of 110 patients diagnosed with MASLD complicated by dyslipidemia received pemafibrate at a dose of 0.1 mg twice daily for 48 weeks., Results: The participants were 54 males and 37 females, with a median age of 63 (52-71) years. Besides improvement in lipid profile, significant reductions from baseline to 48 weeks of treatment were found in liver-related enzymes, such as aspartate aminotransferase, alanine aminotransferase (ALT), gamma-glutamyl transpeptidase, and alkaline phosphatase ( P < 0.001 for all). A significant decrease in the homeostasis model assessment-insulin resistance (HOMA-IR) was observed in patients with insulin resistance (HOMA-IR ≥ 2.5) (4.34 at baseline to 3.89 at Week 48, P < 0.05). Moreover, changes in ALT were weakly correlated with those in HOMA-IR ( r = 0.34; p < 0.05). Regarding noninvasive liver fibrosis tests, platelets, Wisteria floribunda agglutinin-positive Mac-2-binding protein, type IV collagen 7s, and the non-alcoholic fatty liver disease fibrosis score significantly decreased from baseline to Week 48. Most adverse events were Grades 1-2, and no drug-related Grade 3 or higher adverse events were observed., Conclusion: This study demonstrated that 48-week pemafibrate administration improved liver-related enzymes and surrogate marker of liver fibrosis in patients with MASLD. The improvement of insulin resistance by pemafibrate may contribute to the favorable effect on MASLD complicated by dyslipidemia., (© 2024 The Authors.

- Abstract
Aim: Elderly patients are believed to have a reduced immune capacity, which may make immunotherapy less effective. The aim of this study was to compare the therapeutic outcome of atezolizumab plus bevacizumab (Atez/Bev) and lenvatinib (LEN) for advanced hepatocellular carcinoma (HCC) in patients aged 80 years and older., Methods: From March 2018 to July 2022, 170 and 92 elderly patients who received LEN and Atez/Bev as first-line treatment, respectively, were retrospectively analyzed., Results: The median ages of the Atez/Bev and LEN groups were 83.0 (8.01-86.0) and 83.0 (82.0-86.0) years (p = 0.3), respectively. Men accounted for approximately 70% of the patients in both groups. The objective response rate was 35.9% in the LEN group and 33.7% in the Atez/Bev group (p = 0.8), whereas the disease control rates in the LEN and Atez/Bev groups were 62.9% and 63.0%, respectively (p = 1.0). The median progression-free survival (PFS) in the LEN and Atez/Bev groups was 6.3 and 7.2 months, respectively, which were not significantly different (p = 0.2). The median overall survival (OS) was 17.9 months in the LEN group and 14.0 months in the Atez/Bev group. This difference was not statistically significant (p = 0.7). In multivariate analyses, the choice of treatment (LEN vs. Atez/Bev) showed no association with PFS or OS. The Atez/Bev group had a significantly higher rate of postprogression treatment (59.0% vs. 35.7%, p = 0.01) and a lower rate of discontinuation due to adverse events (69 [40.6%] vs. 19 [20.7%], p < 0.001) compared to the LEN group., Conclusions: Atezolizumab plus bevacizumab showed comparable effectiveness to LEN in HCC patients aged 80 years and older. Given the results of postprogression treatment and discontinuation due to adverse events, Atez/Bev could serve as a first-line treatment even for elderly HCC patients., (© 2023 Japan Society of Hepatology.)

- Abstract
Background: Hamstring muscles are the most frequently reported sites of muscle strain injuries, especially near the bi-articular muscles' myotendinous junction, where aponeurosis provides a connective tissue network linking muscle fibers to the tendon. This study aimed to investigate the reliability and site-specific differences of hamstring aponeuroses under different conditions (formalin and urea) using MyotonPRO., Methods: Eight hamstring muscle groups were dissected from four human cadavers (two males and two females) aged 83-93 years. Measurements of the mechanical properties of the aponeuroses from the superficial and deep regions of biceps femoris long head, semitendinosus, and semimembranosus (after formalin solution immersion) were done using MyotonPRO (intra-rater reliability was examined within a 24-h interval), following which the hamstring aponeuroses were measured using a similar procedure after urea solution immersion., Findings: Test-retest (intra-rater) results revealed that the MyotonPRO measurement of tone, stiffness, relaxation, and creep of cadaveric aponeuroses presented good to excellent reliability (ICC: 0.86 to 0.98). There were no significant differences in tone, stiffness, elasticity, relaxation, and creep among the six sites of hamstring aponeuroses under both formalin and urea conditions. Significant differences between formalin and urea conditions were found in the tone, stiffness, relaxation, and creep of hamstring aponeuroses (P < 0.05)., Interpretation: These results suggested that the biomechanical properties of hamstring aponeuroses showed homogeneity between the sites using MyotonPRO. Urea solution could potentially neutralize the effect of formalin on the biomechanical properties of cadaveric muscle-aponeurosis-tendon units. The present findings might influence the design of subsequent cadaveric studies on hamstring muscle strains., Competing Interests: Declaration of competing interest There is no conflict of interest to declare., (Copyright © 2024 Elsevier Ltd.

- Abstract
Erionite (ERI) zeolite has recently attracted considerable attention for its application prospect in the selective catalytic reduction of NO
x with NH3 (NH3 -SCR), provided that the high-silica (Si/Al > 5.5) analog with improved hydrothermal stability can be facilely synthesized. In this work, ERI zeolites with different Si/Al ratios (4.6, 6.4, and 9.1) are synthesized through an ultrafast route, and in particular, a high-silica ERI zeolite with a Si/Al ratio of 9.1 is obtained by using faujasite (FAU) as a starting material. The solid-state29 Si MAS NMR spectroscopic study in combination with a computational simulation allows for figuring out the atomic configurations of the Al species in the three ERI zeolites. It is revealed that the ERI zeolite with the highest Si/Al ratio (ERI-9.1, where the number indicates the Si/Al ratio) exhibits a biased Al occupancy at T1 site, which is possibly due to the presence of a higher fraction of the residual potassium cations in the can cages. In contrast, the Al siting in ERI-4.6 and ERI-6.4 proves to be relatively random., (© 2024 The Authors. Advanced Science published by Wiley‐VCH GmbH.)- Published

- Abstract
Aims: The aim of the present study was to elucidate detailed parameters for prediction of prognosis for patients with unresectable hepatocellular carcinoma (uHCC) receiving atezolizumab plus bevacizumab (Atez/Bev) treatment., Methods: A total of 719 patients (males 577, median age 74 years) treated with Atez/Bev between September 2020 and January 2023 were enrolled. Factors related to overall survival (OS) were extracted and a prognostic scoring system based on hazard ratio (HR) was created. OS and progression-free survival (PFS) were retrospectively examined, and the prognostic ability of the newly developed system was compared to CRAFITY score using concordance index (c-index) and Akaike information criterion (AIC) results., Results: Cox-hazards multivariate analysis showed BCLC classification C/D (HR 1.4; 1 point), AFP ≥100 ng/mL (HR 1.4; 1 point), mALBI 2a (HR 1.7; 1 point), mALBI 2b/3 (HR 2.8; 2 points), and DCP ≥100 mAU/mL (HR 1.6; 1 point) as significant factors. The assigned points were added and used to develop the IMmunotherapy with AFP, BCLC staging, mALBI, and DCP evaluation (IMABALI-De) scoring system. For IMABALI-De scores of 0, 1, 2, 3, 4, and 5, OS was not applicable (NA), NA, 26.11, 18.79, 14.07, and 8.32 months, respectively (p < .001; AIC 2788.67, c-index 0.699), while for CRAFITY scores of 0, 1, and 2, OS was 26.11, 20.29, and 11.32 months, respectively (p < .001; AIC 2864.54, c-index 0.606). PFS periods for those IMABALI-De scores were 21.75, 12.89, 9.18, 8.0, 5.0, and 3.75 months, respectively (p < .001; AIC 5203.32, c-index 0.623) and for the CRAFITY scores were 10.32, 7.68, and 3.57 months, respectively (p < .001; AIC 5246.61, c-index 0.574). As compared with CRAFITY score, IMABALI-De score had better AIC and c-index results for both OS and PFS., Conclusion: The present results indicated that the proposed IMABALI-De score may be favorable for predicting prognosis of uHCC patients receiving Atez/Bev therapy., (© 2024 The Authors.

- Abstract
Sarcopenia frequently and progressively occurs in patients with chronic liver disease. This study aimed to clarify the relationship between vitamin D levels and muscle mass loss. A total of 166 patients with chronic liver disease were enrolled in this study. Skeletal muscle mass index (SMI) was measured by bioelectrical impedance analysis at baseline and after 1 year. The rate of change in SMI from baseline after 1 year was calculated: ΔSMI (%) = [(1-year SMI - baseline SMI) / baseline SMI] × 100. Muscle mass loss was defined as ΔSMI ≤ -2%. The median 25-hydroxyvitamin D was 15.2 (11.2-19.3) ng/mL. The median SMI were 6.8 (5.9-7.8) kg/m2 at baseline and 6.7 (5.9-7.6) kg/m2 after 1 year. The median ΔSMI was -1.23% (-2.21% to 1.61%). Multivariate analysis identified low 25-hydroxyvitamin D as an independent factor associated with muscle mass loss. The optimal cut-off value of 25-hydroxyvitamin D to predict muscle mass loss was 12.7 ng/mL. Muscle mass loss was found in 56.4% v.s. 18.0% of patients with 25-hydroxyvitamin D < 12.7 vs. ≥ 12.7 ng/mL, respectively (p = 9.01 × 10-7); with the highest incidence in patients with non-alcoholic fatty liver disease (NAFLD). Specifically, patients with NAFLD and 25-hydroxyvitamin D < 12.7 ng/mL had a significantly higher incidence of muscle mass loss than those with ≥ 12.7 ng/mL (p = 1.23 × 10-3). Low vitamin D levels are associated with muscle mass loss after 1 year in patients with chronic liver disease, especially NAFLD., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Okubo et al.
